Question

我有以下标记，其中包含3个内容块，每个内容包含一个标题和一些内容：

<div class="feed-panels-expanding">
    <div class="feed">

        <section>

            <h2><a href="#">Heading One</a></h2>
            <p>Ut in nulla enim. Phasellus molestie magna non est bibendum non venenatis nisl tempor. Suspendisse dictum feugiat nisl ut dapibus. Mauris iaculis porttitor posuere. Praesent id metus massa, ut blandit odio. Proin.</p>

            <div class="content">
                <p>Duis aliquet egestas purus in blandit. Curabitur vulputate, ligula lacinia scelerisque tempor.</p>
                <p>Lacus lacus ornare ante, ac egestas est urna sit amet arcu. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos.

                <p>Proin vel ante a orci tempus eleifend ut et magna. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vivamus luctus urna sed urna ultricies ac tempor dui sagittis.</p>
            </div>

        </section>

        <section>

            <h2><a href="#">Heading Two</a></h2>

            <div class="content">

            </div>

        </section>

        <section>

            <h2><a href="#">Heading Three</a></h2>
            <p>Ut in nulla enim. Phasellus molestie magna non est bibendum non venenatis nisl tempor. Suspendisse dictum feugiat nisl ut dapibus. Mauris iaculis porttitor posuere. Praesent id metus massa, ut blandit odio. Proin.</p>

            <div class="content">
                <p>Duis aliquet egestas purus in blandit. Curabitur vulputate, ligula lacinia scelerisque tempor.</p>

        </section>

    </div>
</div>

我想要它，以便点击每个标题可以扩展/关闭下面的内容。

我正在努力让jQuery脚本负责隐藏除第一段之外的所有内容。为了做到这一点，它需要第一段并将其移到.content之外。然后隐藏.content

// feed-panels-expanding
$('.feed-panels-expanding section').each(function() {

    $(this).find('h2 a').click(function() {
        $(this).parent().next('.content').slideToggle(250);
        return false;
    });

    $(this).find('.content p:first').insertAfter($(this).find('h2'));
    $(this).find('.content').hide();

});

然而，脚本真的不喜欢我在每个内容块中移动第一个p元素。如果我删除该行，脚本工作正常，并且在单击相关标题时所有面板都会展开/收缩。

但是那里有那行代码，脚本什么都不做。点击标题后我可以弹出一个alert语句，但它只是忽略了.content个元素

Answer 1

next()在您选择的元素之后查找下一个元素。它不再是content元素。下一个元素是您刚刚插入的段落。

$(this).parent().siblings('.content').slideToggle(250);

Answer 2

next 仅查看以下单个兄弟元素，然后应用过滤器。

现在简单修复。将nextAll与.content过滤器一起使用：

$(this).find('h2 a').click(function() {
    $(this).parent().nextAll('.content').slideToggle(250);
    return false;
});

nextAll仅查看后续元素，因此当您知道后续元素后，效率会高于siblings。

Answer 3

这是working jsfiddle。

除了第一个内容div之外，所有内容div最初都是隐藏的。无需删除它并将其放在其他位置 - CSS可以通过查找第一个section元素然后在其中找到.content div来找到它。

对于jQuery，click事件会查找section父元素，然后在其中搜索.content div来切换显示。

Answer 4

我认为您的问题是选择内容检查代码段

你做了$（this）.parent（）女巫是h2标签而不是.content并使用find更好地找到元素.content

$(this).parent().parent().find('.content').slideToggle(250);

＆＃13;

// feed-panels-expanding
$('.feed-panels-expanding section').each(function() {

    $(this).find('h2 a').click(function() {
      //you did $(this).parent() witch is the h2 tag not the scetion and use find better
        $(this).parent().parent().find('.content').slideToggle(250);
        return false;
    });

    $(this).find('.content p:first').insertAfter($(this).find('h2'));
    $(this).find('.content').hide();

});
